Allen Bradley 1746-OB32 SLC 500 Digital DC Output Module

Product Introduction

The Allen-Bradley 1746-OB32 is a high-density DC digital output module designed for the SLC 500 programmable controller platform. It provides efficient and reliable switching of DC loads, making it well-suited for applications requiring a large number of output points within a compact control system.

This module features 32 transistor-based sourcing output channels, enabling it to control multiple field devices simultaneously. It is designed to deliver 5–50V DC output signals, making it compatible with a wide range of industrial DC loads such as relays, solenoids, indicator lights, and small actuators.

With its open-style configuration, the 1746-OB32 allows flexible wiring and straightforward integration into control systems. Its solid-state transistor outputs ensure fast switching, minimal wear, and long-term operational stability. The module is commonly used in automation systems where high output density and reliable DC control are required.
